/*

This program reads the DAQ data files passed as argument using the monitoring library.

It computes the average event size and populates local "./result.txt" file with the 
result.

The program reports about its processing progress.

Messages on stdout are exported to DAQ log system.

DA to write mapping for the ZDC ADCs
